<h4><a name = "tag_000_001_413">&nbsp;</a>NAME</h4><blockquote>
cfsetispeed - set input baud rate
</blockquote><h4><a name = "tag_000_001_414">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="termios.h.html">termios.h</a>&gt;

int cfsetispeed(struct termios *<i>termios_p</i>, speed_t <i>speed</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_001_415">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>cfsetispeed()</i>
function sets the input baud rate stored in the structure pointed to by
<i>termios_p</i>
to
<i>speed.</i>
<p>
There is no effect on the baud rates set in the hardware until a
subsequent successful call to
<i><a href="tcsetattr.html">tcsetattr()</a></i>
on the same
<b>termios</b>
structure.
</blockquote><h4><a name = "tag_000_001_416">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion,
<i>cfsetispeed()</i>
returns 0.  Otherwise -1 is returned,
 and
<i>errno</i>
may be set to indicate the error.
</blockquote><h4><a name = "tag_000_001_417">&nbsp;</a>ERRORS</h4><blockquote>
The
<i>cfsetispeed()</i>
function may fail if:
<br>
<dl compact>

<dt>[EINVAL]<dd>
The
<i>speed</i>
value is not a valid baud rate.

<dt>[EINVAL]<dd>
The value of <i>speed</i> is outside the range of possible
speed values as specified in
<i><a href="termios.h.html">&lt;termios.h&gt;</a></i>.

</dl>
